Thanks for choosing Tumblr, a place to connect with others over shared interests. In order to provide you with the best possible experience, we occasionally update the app to squash bugs and speed things up.

Don't forget to follow @staff for updates, feature announcements, and a heck of a lot of fun.

Tumblr is a place to express yourself, discover yourself, and bond over the stuff you love. Whether it’s fandoms or philosophy, fashion or felines, Tumblr is where your interests connect you with your people.

EXPRESS YOURSELF
— Post photos, GIFs, text, videos, live videos, audio, anything.
— Make your own GIFs. Cover them in stickers and text, if you like.

CONNECT WITH YOUR PEOPLE
— Join millions of people in millions of communities across millions of #tags.
— See something you love? Reblog it to your Tumblr and start a conversation.
— Start a private conversation with your friends in messaging.
— Or just follow, if you’re feeling shy. No big deal.
